1 / 51 page  MP2733 Wide Input Range, 4.5A, I2C-Controlled SW Charger with NVDC Power Path and USB OTG and Enhanced ADC MP2733 Rev. 1.1 www.MonolithicPower.com 1 5/18/2023 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2023 MPS. All Rights Reserved. DESCRIPTION The MP2733 is a 4.5A, highly integrated switch- mode battery charger management device for single-cell Li-ion or Li-polymer batteries. This device works with narrow voltage DC (NVDC) system power path management, and is well- suited for a variety of applications, including smartphones, tablets, wireless cameras, and other portable devices. Its low-impedance power path optimizes efficiency, reduces battery charging time, and extends battery life. The I2C interface allows the device to be flexibly controlled with configurable charging and system settings. The MP2733 supports a wide range of input sources, including standard USB host ports and high-powered wall adapters with fast charge capabilities. The MP2733 provides USB input type detection via the DP/DM pins. The device supports USB On-the-Go (OTG) operation by supplying 5V on the input bus, with an output current limit up to 3A. The MP2733 initiates and completes a charging cycle without software control. It automatically detects the battery voltage and charges the battery in different stages. Charging automatically terminates when a full charge is detected. When the charged battery drops below the recharge threshold, the charger automatically begins another charging cycle. The charger provides various safety features for battery charging and system operations, including a charging safety timer, battery temperature monitoring, and over-voltage protection (OVP), and over-current protection (OCP). If a fault occurs, the charger asserts an INT signal to the host. The device provides BATTFET disable control to enter shipping mode, as well as system reset functionality via the DISC pin. The MP2733 is available in a QFN-26 (3.5mmx3.5mm) package. FEATURES • 3.7V to 16V Operating Input Voltage Range • Up to 22V Sustainable Voltage • High-Efficiency, 4.5A, 1.35MHz Buck Charger with Up to 92% Charge Efficiency with 3A Charge Current: o Configurable D+/D- for Flexible Fast Charge Protocol Support • USB OTG with 4.8V to 5.5V Adjustable Output: Up to 3A Output, Up to 93% Efficiency with 1.5A Output • NVDC Power Path Management o Instant-On Works with No Battery or Deeply Discharged Battery o Ideal Diode Operation in Battery Supplement Mode • High Battery Discharge Efficiency with 14mΩ BATTFET Up to 8.5A • I2C Interface for Flexible System Parameter Setting and Status Reporting • Fully Integrated MOSFETs, Current Sensing • Dedicated DISC Pin to Control Shipping Mode and System Reset • 13µA Low Battery Leakage Current in Shipping Mode • Integrated ADC Monitors Input Voltage and Current, Battery Voltage, Charge Current, System Voltage, and Battery Temperature • Charging Status Indicator • Safety Features: Configurable JEITA for Battery Temp Protection in Charge Mode, Battery Charging Safety Timer, Thermal Regulation and Shutdown, Watchdog Monitoring I2C, and Input/System OVP • Available in a QFN-26 (3.5mmx3.5mm) Package APPLICATIONS • Tablet PCs • Smartphones • Wireless Cameras • Other Portable Devices All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
